[Polygon Launches Polygon CDK Besu, Supporting Institutional Private Chain Integration with Agglayer] Polygon has launched Polygon CDK Besu, enabling banks and financial institutions to deploy private blockchains based on Hyperledger Besu and integrate with other blockchains and liquidity through Agglayer. It currently supports deployment on the Ethereum mainnet. This solution adopts the QBFT consensus mechanism, allowing institutions to manage validator nodes and transaction permissions, verify cross-chain asset transfers using zero-knowledge proofs, and settle on Ethereum. Transaction data is retained within the institution's private infrastructure without needing to be uploaded to Ethereum. Institutions already running Hyperledger Besu can directly integrate with Agglayer.
